維修中需要注意一下幾點(diǎn)拆卸、儀表時(shí)，應(yīng)記錄原來的位置，以便復(fù)原。在下檢修無紙記錄儀故障時(shí)，對(duì)印刷線路用萬用表測(cè)其各點(diǎn)是否通暢很有必要，因?yàn)檫@種情況下的主要故障是銅箔腐蝕。用萬用表歐姆擋時(shí)，切記不要帶電測(cè)量。修理精密無紙記錄儀時(shí)，如不慎將小零件彈飛，可采取磁鐵掃描和視線掃描進(jìn)行尋找。檢測(cè)電源中的濾波電容時(shí)，應(yīng)先將電解電容器的正負(fù)極短路一下，而且短路時(shí)不要用表筆線來代替導(dǎo)線對(duì)電容器進(jìn)行放電，因?yàn)檫@樣容易燒斷芯線。可以取一只帶燈頭引線的220V，60～100W的燈，接于電容器的兩端，在放電瞬間燈泡會(huì)閃光。檢修無紙記錄儀內(nèi)部電路時(shí)，如果安裝元件的接點(diǎn)和電路板上涂了絕緣清漆。ASFLOW公司以半導(dǎo)體工序用高純管道配件的專業(yè)性為基礎(chǔ), 開啟了高純閥門及過濾器事業(yè), 2018年銷售額達(dá)到了567億韓元（出口150億韓元), 近5年平均銷售額增長(zhǎng)率為32.7%，正實(shí)現(xiàn)迅速增長(zhǎng)。
